SWITCH-STAND.

SPECIFICATION forming part of Letters Patent No. 315,011 dated April 7,1885.

Application filed February 16, 1884. (No model.)

To all whom it may concern:

Be it known that I, LEWIS M. CURRY, a citizen of the United States,residing at Jackson, county of Jackson, State of Michigan, have inventeda new and useful Switch-Stand, of which the following is aspecification.

My invention has for its object certain inr provenients in such devicesto increase their utility and insure greater safety.

In the accompanying drawings forming a part of this specification,Figure 1 is a side elevation with parts broken away and thedraw-bardetached; Fig. 2, a top and sectional view looking down from line 2 2 inFig. 1; Fig. 3, a broken portion of Fig. l in vertical section on line 11 in Fig. 2,- Fig. 4,, a side elevation of a part of Fig. 1, showing theside opposite to that in said figure; Fig. 5, same as Fig. 2,with partsremoved; Fig. 6, a plan of a switch and a section on line 3 3 in Fig. 1;and Fig. 7 an enlarged perspective of a part Fig. 6.

The leaning standards B of the stand are provided with a base-plate,D,and a top plate,- a. The top plate has a central hole, 6, in which theround hearing or axle c of the ro tatable carriage c is located.

Through a square hole in the carriage and its axle c the perpendicularsignal-shaft P is located.

a u are notches to receive the pivoted lever r, as in otherswitclrstands. In addition to this mode of locking,which is deemedunsafe,

I have provided the carriage c with a verti-- cally-falling pin-lock,f,adapted to enter holes or in the top plate, Figs. 5 and 3. WVith thisconstruction the pin f and lever r are raised, as in Fig. 4, and thecarriage and signal shaft are turnedto the desired position, when thelock-pin will fall by its own weight to the position shown in Fig. 3.The lower part of the lock-pinf is enlarged, forming a shoulder at thetop of said enlarged portion adapted to intercept the upper end of therecess d, and prevent the lock-pin from being drawn out when raising it.

The carriage is provided with afiange, e,to cover the lock-holes w. ttare stops to limit the movement of the carriage.

The upper portion of the shaft P is provided with the usual day andnight signals, A and L. The lower end of the standard P terminates in acrank, 3

The base-plate D is provided with a notch' or recess, o, beneath theends of the crank y when said crank is in the position shown in Fig. 6.draw-bar h, which is perforated for the pur pose,can be inserted in therecess 11 and slipped over the end 8 of the crank. The draw-bar at thistime is in the position shown by the broken bar h in dotted lines inFig. 6. By

By this means the end of the switch v connection of the top of the standis had with said shaft, and the base of the standards does not conflictwith the operating means connected with the lower end of the verticalshaft P. (See Figs. 6 and 1.)

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The stand having the upper plate provided with the lock-holes,incombination with a carriage adapted to rotate, and provided with alock-pin and with a base-flange adapted to cover said lock-holes,substantially as described.

2. The combination,in a switch-stand,of the plate provided with thelock-holes, the carriage provided with the-lock-pin recess, and alock-pin having the shoulders adapted as set forth, substantially asdescribed.

In testimony of the foregoing I have hereunto subscribed my name in thepresence of two witnesses.
